AKROMID® B3 GM 10/20 1 L black (4646) is a 10% glass fibre reinforced, 20% glass bead filled and heat stabilised polyamide-blend with a reduced density compared to standard PA6 GF10 + GB20

Typical applications

Optical components in the automotive and electronic industry, where a weight and cost reduction is required

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
